The Need To Strengthen The Icao Provisions Relating To Bird Control On And In The Vicinity Of Airports, Alistair Pinos

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Bird strikes to aircraft are a threat the safety of aviation and as air traffic continues to grow, their numbers appear to be increasing,. In 1965 ICAO began to monitor bird strikes through the collection of bird strike reports as it became clear that the turbine engined aircraft coming into wider use were more susceptible to bird strike damage than their predecessors. This data collection became automated in 1980 with the creation of the ICAO Bird Strike Information System (IBIS), which now contains information on more than 80 000 bird strikes. When IBIS was created, it was thought that approximately …

Pbi/Gordon’S Stronghold™ Plus Bk 800 Broadleaf Weed Control Reduces Mowing, And Eliminates Grass And Weed Seedheads, Earl Tracy

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

We entered the birdstrike arena last year at the Burke Lakefront Airport just prior to the 1998 Bird Strike Committee meeting. Stronghold was applied tank-mixed with Flight Control™ Bird Repellent from Environmental Biocontrol, International ,Wilmington, Delaware. The initial test on the airport was not conclusive, but the idea of the combination appealed to Dr. Richard Dolbeer, Project Leader, USDA , National Wildlife Research Center, Sandusky, Ohio. A second trial plot was established on government property at Sandusky, Ohio. The objective being to quantify the value of Stronghold to the bird repellent activity of Flight Control. The results are to be …

The German Military Geophysical Service. Bird Migration Observation, Warning And Forecasting System: New Developments Towards An Automated Bird Migration Information System, Wilhelm Ruhe

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The German Military Geophysical Office (GMGO) has a more than 30-years experience in all fields of bird strike prevention. Military training and flight operations usually take place in low altitudes, where also a lot of birds are present, especially near coasts and during migration periods. About one third of all the GAF bird strikes occurs during low level flight operations. The most effective tool for bird strike prevention in military low level flying is the well proved system of
· continuous actual bird migration observation (visual and by radar),
· immediate reporting,
· centralised risk evaluation,
· online warning (BIRDTAM), …

Management Of The Yellow Bittern (Ixobrychus Sinensis) On Guam To Minimize Threats To Aviation Safety, Daniel S. Vice, Mikel E. Pitzler

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Wildlife-aircraft collisions caused an estimated $114 million of damage annually to civilian aviation aircraft in the United States between 1993 and 1995 (Cleary et al. 1996). Significant damage to aircraft and crashes may result from the ingestion of one small bird (Cleary et al. 1996). Collisions that do not cause physical damage to aircraft often result in costs related to aircraft downtime while structural inspections are completed. Despite heightened awareness of the hazards wildlife present to aircraft, strikes occur often and occasionally have catastrophic results. The yellow bittern (Ixobrychus sinensis) is a common breeding bird throughout the western Pacific. Yellow …

Thermal Imagery Applied To Reducing Bird Hazards To Aircraft At Airports, James R. Ivey Cpt.

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Airports worldwide are at a disadvantage when it comes to being able to spot birds and warn aircrews about the location of flocks either on the ground or close to the airfield. Birds simply cannot be easily seen during the day and are nearly invisible targets for planes at night or during low visibility. Thermal imaging (infrared) devices can be used to allow ground and tower personnel to pinpoint bird locations day or night, thus giving the airport operators the ability to launch countermeasures or simply warn the aircrews. This technology is available now, though it has been predominately isolated …

A Fixed Netting System As A Means Of Excluding Birds From A Domestic Waste Landfill, Vicky S. Jackson, J. Brown, J. R. Allan

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Many bird species are attracted to landfills which take domestic or putrescible waste. These sites provide a reliable, rich source of food which can attract large concentrations of birds. The birds may cause conflicts with human interest with respect to noise, birds carrying litter off site, possible transmission of pathogens in bird droppings and the potential for birdstrikes. In the UK there is an 8 mile safeguarding radius around an airfield, within which any planning applications must pass scrutiny from regulatory bodies to show they will not attract birds into the area and increase the birdstrike risk. Peckfield Landfill site …

Integrated Management Systems For Australian White Ibis (Threskiornis Molucca) On The Gold Coast, Queensland, Australia, Phillip P. Shaw

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Fueled by a large supplemental food supply at landfills in South-east Queensland, Australian White Ibis (Threskiornis molucca) populations grew from an estimated 5000 to 10000 between 1995 and 1998. Ibis counted at Coolangatta Airport reflected this growth with a 556% increase between 1989 and 1995. The multimillion-dollar loss of a Qantas airbus engine from ingestion of an Ibis, resulted in the establishment of the Ibis Management Coordination Group (IMCG). This group, comprising government, industry and community representatives, instigated an integrated program of food reduction, restriction of breeding success and public education. The program has become an example for management programs …

The Use Of Night Landfilling To Reduce Bird Hazards To Aircraft Safety, Rolph A. Davis, Joseph Mangino

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The Atlantic County Utilities Authority (ACUA) operates a ‘bulky waste’ (non-putrescible waste) landfill at a site that is 10,300 ft from the end of the main runway at the Atlantic City (NJ) International Airport (ACY). The airport supports the Federal Aviation Administration’s Technical Center. The ACUA also operates a transfer station at its site. Municipal solid waste (msw = putrescible) is delivered to the transfer station during the day. Previously, the msw was loaded onto transfer trucks and shipped to an out-of-state landfill. In October 1997, the ACUA received a permit to conduct a 2-year experiment to dispose of the …

Complete Control Of Nuisance Birds In Airport Hangars, Peter F. Vogt

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Fogging of ReJeX-iT7 TP-40 offers a very efficient method for the control and dispersal of nuisance birds from many diverse areas. The amount of the repellent is greatly reduced over any other control method. The method is direct and is independent of the activity of the birds. The applications with any fogger, thermal or mechanical, that can deliver droplets of less than 20 microns, can be manually or fully automated and pose only minimal risks to operators or animals. All birds that became a nuisance and safety problem in the hangars of TWA and AA at LaGuardia, and TWA warehouse …

Zero Bird-Strike Rate - An Achievable Target, Not A Pipedream, S. M. Satheesan

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

This paper explains how zero bird-strike rate can be achieved by any aerodrome by constant efforts and perseverance of a dedicated team as evidenced from the author’s experience on about 30 aerodromes in India. This paper stresses the importance of conducting survey of problem aerodromes every five years by an expert (Satheesan 1996c), necessity for employing an Ornithologist at every aerodrome, need for regular national-level training for bird-controllers (Satheesan, in press - b) and urgency for setting up Bird-strike Prevention Committees at national (interministerial) and airport levels. Bird strike rates were brought down to zero at the Trivandrum International Airport …

Coping Strategies For The Aircraft Birdstrike Problem: Resisting Impacts, Avoiding Collisions, And …, R. J. Speelman Iii, M. E. Kelley, R. E. Mccarty, J. J. Short

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

When birds and aircraft occupy the same airspace at the same time, bad things happen. Annual DoD costs probably exceed $200 Million per year, and dollar losses to world-wide aviation have been estimated at $3 Billion to $4 Billion per year (in US dollars). Much has been done in the past to improve the bird impact resistance of aircraft, and some further improvements would be cost effective on some aircraft. A new manufacturing technology for aircraft transparencies that can increase strength while slashing costs by 80% is one promising approach. However, the “law of diminishing returns” comes into play, and …

Evaluation Of Controlling Red-Tailed Hawks (Buteo Jamaicensis) Through Live Trapping And Relocation To Minimize Aircraft Strikes At Canadian Airports, Martin L. Wernaart, Terri L. Groh, Philip J. Roberts

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Central and Southwestern Ontario is one of the largest migratory flyways for raptors in North America. The expanse of airfields and prey availability make airfields attractive to migrating raptors, which may result in an increase in over wintering birds. These birds do not readily scare with conventional wildlife control methods and have high public profile. Even though the strike risk is moderate, raptors routinely make the top ten list for strikes from all bird species (8%) at Canadian Airports. The potential for damage from a collision with raptor species is high due to their size and weight. It has been …

Bird Strike Risk Analysis On Aktion Airfield (Greece) And Recommendations For Improvements In Bird Strike Prevention, Heinrich Weitz

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

A survey of Aktion airfield in Greece was carried out from 14 to 18 October 1996 initiated by the Flight Safety Division of the NATO E-3A Component Geilenkirchen (Germany) as an reaction to the accident of an AWACS-aircraft on 14. July 1996, initially caused by a bird strike event. The survey of Aktion airfield led to the conclusion that the bird strike risk is extremely high at this airfield. Reasons are:
· The geographical location of the airfield at the Adriatic coast which is a migratory pathway for many birds.
· The location of the airfield on a narrow peninsula …

Private Industry Initiative At Bird Control: A Success Story, Nick Barnes, Rhian Christie, Stan Kruse

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

An increase in land development pressures and land use conflicts in urban centres with airports requires that a greater priority be placed on bird control and wildlife management. This is a particularly high concern for the siting and operation of landfills. Minimizing the potential for bird/wildlife interactions with aircraft is critical to maintaining air traffic safety. Browning-Ferris Industries (BFI) has demonstrated a corporate sensitivity to the bird management issue. A corporate commitment has been made to address the issue of bird management at waste management facilities in the vicinity of airports. This paper provides an overview of two case studies …

Temporal And Spatial Patterns Of Avifauna On Wetlands In The Vicinity Of Bush Field Airport, Augusta, Georgia, Usa, Robert A. Kennamer, L. Brisbin Jr., K. F. Gaines, W. L. Stephens Jr.

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Responding to a U.S. Federal court order to improve discharged wastewater quality, Augusta, Georgia initiated development of artificial wetlands in 1997 to treat effluents. Because of the proximity to Augusta Regional Airport at Bush Field, the U.S. Federal Aviation Administration expressed concern for potential increased hazard to aircraft posed by birds attracted to these wetlands. We commenced weekly low-level aerial surveys of habitats in the area beginning January, 1998. Over a one-year period, 49 surveys identified approximately 42,000 birds representing 52 species, including protected Wood Storks and Bald Eagles, using wetlands within 8 km of the airport. More birds were …

Close-Range And Satellite Remote Sensing Of Algal Biomass In The Iowa Great Lakes, Eric A. Wilson

Department of Geography: Dissertations, Theses, and Student Research

The utility of both close-range and satellite remote sensing for assessing inland water quality was examined in the Iowa Great Lakes. The water quality of this system is of considerable interest because of its status as an environmental, recreational, and therefore, economic resource. The broad range of optical conditions present in the lakes and the wealth of literature on the system make it an ideal environment for water quality remote sensing research. The goal of this research was to survey the water quality of the Iowa Great Lakes via remote sensing, evaluate different predictive algorithms, and map the distribution of …

An Assessment Of The World-Wide Risk To Aircraft From Large Flocking Birds, J. R. Allan, J. C. Bell, V. S. Jackson

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The difficulties encountered in interpreting the available data, which arise from incomplete or inaccurate information being submitted, or from inconsistent reporting by national organisations, illustrate the importance of recording and reporting birdstrike incidents. Even allowing for the fact that birdstrikes with large birds, and especially those with flocks, are more likely to be reported, it is probable that the database established for this project contains only a fraction of the incidents that have actually occurred. Nevertheless, some broad conclusions can be drawn from the data available, and as more data are collected, predictions and estimates can be refined and the …

Pigeon And Crows Population Control By Trapping, Ben (Ze'ev) Foux

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Feral pigeons (Columba Livia) are a safety problem all around the airdrome, as they fly in big, dense flocks crossing the runways. Pigeons are also one of the worst causes of foreign object damage in the hangars and are an environmental and health hazard. The hooded crow is found around runways in Israeli air-bases, due to the thick vegetation that can be found in the bases. Other methods for bird population control in use now involve either repulsing (glue, spikes, nets) or eliminating (poison, shooting). Trapping is an environmental friendly, cost-effective long term solution, with a history of thousands of …

The Effects Of Changes In The Northern Lapwing Population On The Bird Strike Hazard In The Uk, J. C. Bell

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Changes in bird populations have been recognised as affecting the risk to aircraft of a bird strike. However, in terms of bird strike prevention, changes are generally only considered at the local level i.e. reducing the number of birds on the airfield. At a national level, concern has been expressed about recent increases in waterfowl, particularly geese, and the implications that this may have for flight safety, and management of the risk. However, although work is currently being undertaken to investigate if higher numbers of large waterfowl are causing an increased risk to safety (Allan, Bell & Jackson in press), …

Monitoring The Distribution, Abundance, And Movements Of Birds Near Vancouver International Airport, M. W. Demarchi, G. F. Searing, M. K. Mcnicholl, T. Mochizuki

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The Vancouver International Airport (YVR) is Canada’s second-busiest civil airport and is located on the Fraser River delta—the staging and wintering ground for millions of birds representing many taxonomic groups. Consequently, YVR experiences one of the highest bird-strike rates of any airport in Canada. Since 1994, LGL Limited has investigated and monitored avian ecology as it relates to existing and potential hazards to air-traffic safety at YVR. A formalized monitoring program is on-going. The distribution, abundance, and flight patterns of birds are recorded and summarized by individual species or by taxonomic group. Monthly and semiannual reports present information that depict …

Feather Identification And A New Electronic System For Reporting Us Air Force Bird Strikes, Carla J. Dove

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

The number of bird strike cases received from U.S. Air Force bases for identification has increased from 640 in 1996 to more than 840 in 1998. The additional workload, together with staff shortages on the BASH team, created a need for a more efficient reporting system. Previously, all bird strike remains were funneled through the Safety Center at Kirtland Air Force Base where they were logged into a database, forwarded to the Smithsonian Institution for identification, and then sent back to Kirtland for data entry of results before being returned to field personnel. This system facilitated a bottleneck in the …

Derivation Of A Dummy Bird For Analysis And Test Of Airframe Structures, Chris H. Edge, J. Degrieck

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Certification of aircraft against the birdstrike threat is expensive and time consuming. With the need to reduce design life cycle time and costs with ever more complex structures (materials, geometries and manufacturing methods) yet with no reduction in safety, the possibilities of certification via generic analysis is an attractive proposition. This paper discusses one approach being considered within British Aerospace (BAe). It relies heavily on research activities that have derived extensive data for bird biometrics and innovative testing that can provide mechanical data for bird failure modes unique to military aircraft.

Whilst almost all birdstrike clearance is performed via testing …

The Perspectives Of The Air Line Pilots Association On Strikes Of Wildlife By Aircraft, Paul F. Eschenfelder

Bird Strike Committee-USA/Canada Joint Annual Meeting: 1st (1999)

Strikes of wildlife by aircraft cause thousands of life-threatening incidents, and hundreds of millions of dollars worth of damage to aircraft every year. This hazard is largely preventable, but it has not been properly addressed to date for a variety of reasons. ALPA believes that action should be taken now before a catastrophe occurs.

Collisions between aircraft and wildlife are increasing in frequency in North America due to growth in the number of migratory birds and other wildlife and the increased numbers of aircraft operations. This threat to human safety has manifested itself in several fatal strikes between aircraft and …

Physics and Astronomy Faculty Publications

Parity violation has been studied recently for neutron resonances in ¹¹⁷Sn. The neutron resonance spectroscopy is essential for the analysis of the parity violation data. We have measured neutron resonances in ¹¹⁷Sn for neutron energies from 1 to 1500 eV using the time-of-flight method and the (n,γ) reaction. The sample was enriched to 87.6% ¹¹⁷Sn. Neutron scattering and radiative widths were determined, and orbital angular momentum assignments were made with a Bayesian analysis. The s-wave and p-wave strength functions and average level spacings were determined.

Surface Composition Of CoXNi1-XO Solid Solutions By X-Ray Photoelectron And Auger Spectroscopies, M. W. Nydegger, G. Couderc, Marjorie Langell

Marjorie A. Langell Publications

The surface and bulk compositions of the mixed metal oxide Co_xNi_1-xO have been compared over the entire range of stoichiometry 0 ≤ x ≤ 1. The materials, which were formed as polycrystalline solid solutions, were shown to be well-ordered and homogeneous in the bulk, but tend to deviate in their surface composition for x > 0.6. Auger and X-ray photoelectron spectroscopy gave comparable results and indicated that the surface composition for samples showing deviation from bulk stoichiometry was compatible with the formation of a spinel-like NiCo₂O₄ surface phase. XPS binding energies and spectral …
